[gecode-users] version 3.2: problem compiling examples in Xcode

[serge lemouton]

Hello,

I still have troubles with the framework installed with Gecode 3.2.0.  
(Mac OS 10.5.8)
For an example, when I use the following command line to compile the  
hamming example
g++-4.2  -I.  -fvisibility=hidden -fPIC -Wextra -Wall -pipe -O3 -fno- 
strict-aliasing -finline-limit=3000 -ffast-math -framework gecode -o  
examples/hamming  examples/hamming.cpp

when I launch the example I always get this 2 errors :

-------------
dyld: lazy symbol binding failed: Symbol not found:  
__ZSt16__ostream_insertIcSt11char_traitsIcEERSt13basic_ostreamIT_T0_ES6_PKS3_i
   Referenced from: /Library/Frameworks/gecode.framework/Versions/18/ 
gecode
   Expected in: /usr/lib/libstdc++.6.dylib

dyld: Symbol not found:  
__ZSt16__ostream_insertIcSt11char_traitsIcEERSt13basic_ostreamIT_T0_ES6_PKS3_i
   Referenced from: /Library/Frameworks/gecode.framework/Versions/18/ 
gecode
   Expected in: /usr/lib/libstdc++.6.dylib

Trace/BPT trap
-------------

If it runs well for you, Mauricio, what can be wrong in my setup ?
